Within the past two decades, mass movement hazards involving fast and large soil deforma- tion have increased significantly in frequency and magnitude due to their strong relation to climate changes and global warming. These phenomena often bring along rocks, debris, and heavy materials that can extensively damage and destroy the landscape and infrastructures, causing devastating economic loss, and often, human casualties. The risk of future disasters continues to escalate with the increase of real estate development in sub-urban areas, in- cluding mountainous regions. Further assessment and prediction on such disasters and their countermeasures are, therefore, in high economic demands. One of the most intuitive ways is to install protective structures in mountain slopes and valleys that can hold the materials brought by the moving landslides. While the current state of the art of landslide predic- tion using numerical methods has been mainly dominated by the development of advanced geomechanical models suited for different types of soil materials, e.g. multi-phase unsat- urated soil model, this study focuses more on the interaction of such phenomena with the installed protection structures. Here, an implicit formulation of material point method (MPM) is implemented to model the landslides considering finite strain assumption. Furthermore, a staggered coupling scheme with traditional Finite Element Method is proposed to simu- late accurately and robustly the dynamic force and displacement coupling of soil-structure interaction. All developments of the method are implemented within the Kratos-Multiphysics framework and available under the BSD license. In the future works, a more adequate con- sideration of coupling scheme and material models considering damage and fracture will be investigated before conducting a real-scale landslide simulation.     «
